Track record: None to speak of. In fact, Oh was for a time married to director Alexander Payne, who is 10 years her senior. But oh, there's cougar potential in that come-hither stare. She's also the only tolerable woman on "Grey's Anatomy" these days, and that should count for something!
Cougar role model: Bo Derek. Why? Because Bo's with not-that-much-younger man John Corbett, and they play it low-key, which is exactly what the classy Oh would be wont to do.
